What does it mean? Does anybody know who outputs this string? Is it etherboot or the Linux kernel? I cannot find these strings in the sources, neither in the kernel nor etherboot sources.

[LinuxBIOS] Good JTAG debuggers?
by Carl-Daniel Hailfinger 30 May '06

30 May '06

Hi, can anyone give me a hint where to get a good and affordable JTAG debugger? Or which model I should look for? I might need one for OLPC development. Regards, Carl-Daniel -- http://www.hailfinger.org/

[LinuxBIOS] Question about AMD/Cyrix Geode GX1 based system
by Juergen Beisert 30 May '06

30 May '06

Hi all, I am trying to bring up a small WinCE based terminal with LinuxBios instead. I'm using the eaglelion/5bcm as a starting point. With this the system comes up, starts etherboot, etherboot loads my Linux kernel (up to text "....done") and then nothing more happens. Some things confuses me: .... Devices initialized Copying IRQ routing tables to 0xf0000...done. Verifing copy of IRQ routing tables at 0xf0000...failed Wrote linuxbios table at: 00000000 - 0000017c checksum 2df2 .... I read in the archives that this failure could be solved be undefining CONFIG_COMPRESS. But it did'nt help. Any other hint to solve it? When etherboot starts: ..... Etherboot 5.4.2 (GPL) http://etherboot.org Drivers: RTL8139 Images: ELF Protocols: DHCP TFTP Relocating _text from: [000100e0,000219a0) to [03aee740,03b00000) Boot from (N)etwork or (Q)uit? Probing pci nic... [rtl8139] - ioaddr 0X1000, irq 0, addr 00:30:AA:00:25:1B 100Mbps full-duplex Searching for server (DHCP).....

Does LinuxBIOS needs any preparations/patches on the Linux kernel to boot and run it? I tried with enabled framebuffer console (and activated screen in the Geode) and with console on serial port. Both without success (also I tried 2.4 and 2.6 kernels). Thanks for any help in advance. Juergen

[LinuxBIOS] Intel 386 bios
by Tyler Pohl 29 May '06

29 May '06

I have a 386 - 233Mhz computer. The EEprom bios chip is an AT28c010 (1MB eeprom from Atmel) I would like to install LinuxBios on this machine but I can't seem to find any real good documentation on how to go about configuring and compiling the bios to work for a machine like this. I have figured out how to compile a random motherboard using buildtarget but i don't know exactly where the binary file ends up or how to make it work on a intel 386 or Xbox or whatever i decide to use it. I am a Electronic Engineer but i am having a hard time figuring out how the LinuxBios can be configured properly. Can anyone help me to find good documentation on configure files and what each program is used for in the LinuxBios directory like for example buildtarget, and in the fallback directory buildrom, linuxbios etc. ? Thank You so much for your time. I am very interested in being able to use LinuxBios and will work like nuts to get up to speed in the development of it. I promise !!!! Who ever have been working on LinuxBois to get it where this far you Rock !

Hi when i try to buildtarget i get this message dell800:/home/tyler/LinuxBIOSv2/targets# ./buildtarget /digitallogic/msm586seg No target config file found Tried both /digitallogic/msm586seg and /digitallogic/msm586seg/Config.lb my config files are correct because i downloaded the zipped version and have compare them to the Linux Journel website. Any ideas?

[LinuxBIOS] Coding style
by Carl-Daniel Hailfinger 26 May '06

What coding style is preferred if I want to merge the lzma code into LinuxBIOS? * plain code, as found in upstream sources (a mess) * all unneeded #ifdef sections removed * additionally proper indentation (tab=8) * additionally replaced obfuscated #defines * additionally Lindented to Linux kernel style Also, what types should I use for variables? * u8, u16, u32 * UInt8, UInt16, UInt32 * u_int8_t ... * u_int8 ... * uint8 ... * uint8_t ... * unsigned char, unsigned short, unsigned int Regards, Carl-Daniel -- http://www.hailfinger.org/

Re: [LinuxBIOS] Etherboot (FILO) with SATA on tyan s2895
by Lu, Yinghai 26 May '06

You can not boot from CK804 sata directly with FILO in Etherboot. The code only support Sata that can work on compatible IDE mode. You need to use other media ( network, CF IDE flash) to load kernel with ck804 sata and kexec support, and use kexec to load final kernel in your sata disk.

[LinuxBIOS] selection of compression algorithm
by Carl-Daniel Hailfinger 26 May '06

26 May '06

Hi, what was the motivation to select nrv2b for compression? Speed? Size of decompressor? Coding style? Size File 843910 vmlinux.bin 437684 vmlinux.bin.nrv2b 430890 vmlinux.bin.gz 414679 vmlinux.bin.bz2 357609 vmlinux.bin.7z If the 7z decompressor is less than 80 kb bigger than the nrv2b decompressor, would it make sense to switch?
